Thumbs up

It's been kind of crappy weather around here with the downpours so it has been the perfect time to do the neon coil mod. Everything went smoothly thanks to all the excellent info here (thanks dave0430). I know I previously posted about using automotive boots at the plug ends but I ended up re-using the resistor boots (resistance tests were good on all 4) mainly because they blocked off the area around the plugs to keep debris out. If I have any future problem with them, I'll switch to the automotive boot ends. The bike started up with just a touch of the start button and ran almost perfectly. I may have to adjust the idle speed but I want to take the bike out for a run before I make any adjustments.

Just an observation, I did a spark test before tear down and there was a barely visible spark across the 1/4" gap of the tester. After changing the coils and wires, there was a bright blue spark jumping across a 1/2" gap. The plug wires appeared to be original and were they ever brittle.

Here's to everyone who contributed to this thread. Thanks

Hey guys, I finally tore into my '82 1100 interstate today, and thought I'd post my mistake so hopefully it will save someone else a little time. I did the conversion without taking my upper fairing off, just pulled the tank cover and air box. After getting it all back together, it fired right up. I tried to take it down the road, but as soon as I put a little load on the engine or tried to rev it, it sputtered and acted like it was dropping down to 2 cylinders working. I tore it all back apart, and discovered that there was a green wire that was originally grounded at the front side of the original coil mount. I was kinda working blind because of the upper fairing, and just didn't notice it. I grounded that wire, and now the bike runs better than ever before. One other thing to mention, my bike had a large ceramic resistor, which looked kinda like the ones used in old chevys. I did leave it inline, just in case.
In my opinion, this upgrade is well worth the time and money. I purchased a new coil and a set of bosch plug wires from Herko down in Miami, and including shipping it cost me less than $35.

As for points, probably already done, but may need a resistor to cut back from 12V to 6V to the points.
Most my older stuff had the resistors, when the resister goes bad the points get the full 12V or so and burn up in about 50-100 miles on the larger V8's I had.
File the points and run great for about 50-100 miles then file again, etc... till I get the new resistor somewhere.

I have worked on many GL1200's and I have never seen a CDI box on a 1200. The 1200 has pulse generators which send a signal to the ignition control unit that sends voltage to the coils, but, it does not have CDI (capacitive discharge ignition) unless your bike has been modified somehow.

Smile GL1100 after modification stills looses spark intermitly

I have install new Neion coils , new wires and solder and srink wraped the wires to the coils. The bike now starts very easly and seems to have more power. I had also replaced the CDI because the old ones had melted. Now after running the bike at 65-70 mph for 8-10 miles the bike starts to miss again. Got back home and put spark testers on and the rear cylinders have interminted spark???. When it cools down it runs great again. I feel like I have a wiring issue to the rear cylinder coil. Thanks for the help!

You could have a pulse generator problem or it could be one of you ignitor boxes. Just because the tar melted out of your old ones doesn't mean they are bad. Try swapping one of the old ones with the 3-4 unit.

Dave, I have installed new replacement CDI from RMSTATOR and then put the old ones back on. The bike starts better with the old ones, I will switch them and see if it goes to 1 & 2. What is the Pulse Genarator? Thanks for your help!!

The PGs are in the ignition unit on the rear of the engine under the fuel tank, the vacuum line from #3 carb goes to it.

Got an Orignal Tech Manual from a buddy of mine tonight and will test the Pulse Genarators units tomorrow.I can not find anyone that has a replacement unit, looks like they are a unit by parts break down.

You will have to source a used one probably but the good news is they seldom fail on 1100s.

Tat is a good thing. To get tot the pulse generator you have to pull the swing arm. No huge deal if you have the swing arm bolt removal tool, just a PITA.
